When a shot is released at an angle of 35 degrees, it's path can be modeled by the function:
f(x) = -0.01x^2+0.7x +6.1.
Use the function to determine the shot's maximum distance.
Occurs when f(x) = 0
:
-0.01x^2+0.7x +6.1. = 0
Use the quadratic formula
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
In this problem a=-.01, b=.7, c=6.1
x+=+%28-.7+%2B-+sqrt%28.7%5E2-4%2A-.01%2A6.1+%29%29%2F%282%2A-.01%29+
Do the math and you should get a positive solution ~ 77.8369 max distance
